Constructor Details

ByteBuffer

public ByteBuffer()

Creates new ByteBuffer with capacity 128

ByteBuffer

public ByteBuffer(int size)

Creates a byte buffer with a certain capacity.

toByteArray

public byte[] toByteArray()

Creates a newly allocated byte array. Its size is the current size of this output stream and the valid contents of the buffer have been copied into it.

Returns:

the current contents of this output stream, as a byte array.

setSize

public void setSize(int size)

toString

public String toString()

Converts the buffer's contents into a string, translating bytes into characters according to the platform's default character encoding.

Overrides:

toString in class Object

Returns:

String translated from the buffer's contents.

write

public void write(int b)
           throws IOException

Specified by:

write in class OutputStream

Throws:

IOException

write

public void write(byte[] b,
 int off,
 int len)

Overrides:

write in class OutputStream

getBuffer

public byte[] getBuffer()
